Low-Cost Self-Employed Tax Return for Self-Employed Canadians

Wait for your notice of assessment, then use Change my return in CRA My Account, ReFILE through approved tax software, or mail a T1-ADJ with supporting documents. Adjustments are allowed for the current year and a set number of earlier years; the CRA's Change my return page states the limit. Explain each line you are changing and attach the receipts. A change takes longer to process than an original return, and interest on any extra tax runs from the original due date.

Most residential rentals produce property income, not business income: you collect rent, pay the bills and report the net amount. The rental becomes a business when you provide services well beyond heat, light, parking and laundry, such as meals, cleaning, security or daily turnover, or run enough units with enough activity that it looks like a trade. The distinction matters for capital cost allowance, CPP on the earnings, and how losses are treated.

When you file electronically the software returns a confirmation number, which means the CRA received the return. Acceptance is the next step: the return is assessed and a notice of assessment issued, usually about two weeks after an online filing. CRA My Account shows the return status, the notice and any refund or balance owing. If nothing appears well past that window, confirm the submission actually transmitted rather than filing a second copy.

If you babysit on your own account you are self-employed: report the gross amounts on a T2125 filed with your T1, then deduct reasonable costs such as supplies, activity fees and a share of home expenses where you care for children in your own home. Keep a record of who paid you and when, even if no parent issues a receipt. If a family hires you as their employee and gives you a T4, report it as employment income instead.

Payroll liabilities are amounts you owe because you paid staff but have not yet handed over: income tax, CPP and EI withheld from pay, the employer's share of CPP and EI, and accrued wages and vacation pay. Withheld amounts are held in trust, so late remittance draws penalties and interest. For 2026, CPP is 5.95% each for employee and employer, and EI is $1.63 per $100 for employees with the employer paying 1.4 times that.

Canada does not use tax classes or tax codes the way some other countries do. Your income tax comes from graduated brackets, with federal rates for 2026 running from 14% up to 33% and separate provincial brackets on top, and from the credits you claim on the personal tax credits return you give your employer. In a business setting, tax class usually means a capital cost allowance class, which sets the rate at which you depreciate an asset.

Preschool and nursery school fees generally qualify as child care expenses, because the care lets a parent work, run a business or study. Fees for the educational portion of a program at a school can be excluded, so ask the provider for a receipt that separates child care from tuition. The claim normally goes on the lower-income spouse's return and is capped by the child's age and earned income. See the CRA child care expenses page.

For an unincorporated business the 2025 return was due 15 June 2026 because of self-employment, but any balance owing had to be paid by 30 April 2026. For an incorporated business the T2 return is due six months after the fiscal year end, with the balance due two months after year end, or three months for an eligible Canadian-controlled private corporation claiming the small business deduction. GST/HST returns and payroll remittances run on their own separate schedules.

Child care is a deduction rather than a refund, so what comes back depends on your marginal tax rate: the higher the rate, the more each dollar of eligible care saves you. The deduction is also capped by the age of each child, by what you actually paid, and by a share of the earned income of the person making the claim. Two families paying identical daycare fees can therefore see very different refunds.

A write-off is everyday language for claiming a deduction. A legitimate expense reduces the income you are taxed on, so it saves tax at your marginal rate, not the full amount spent. Only expenses incurred to earn income qualify, they must be reasonable, and you need receipts. Some claims are capped by rule: business meals and entertainment are deductible only in part, and the cap applies to the sales tax and the tip as well as the food, with a few exceptions such as employer-hosted events and long-haul driving.

Taxable revenue is your worldwide revenue from supplies made in Canada that are taxable or zero-rated, measured before expenses. It leaves out exempt supplies such as residential rent and most health services, and it leaves out proceeds from selling capital property. This is the figure tested against the $30,000 small-supplier threshold over four consecutive calendar quarters or within a single quarter; going over in one quarter ends small-supplier status on the sale that takes you past it.

For the 2025 tax year the self-employed filing deadline is 15 June 2026, but any balance owing was still due 30 April 2026. Interest runs on unpaid amounts from the day after the payment deadline even though the return itself is not late, so estimate and pay by the April date and file by June. The later filing date covers you and your spouse if either of you carried on a business. Instalments may also apply through the year.
